Propschick, what sort of system are you running? Do you have at least 2GB of RAM? A fairly fast processor? Lots of hard drive space?

These are considerations, since Poser loves to consume system resources.

If you have ample resources, here is what I would suggest you do.

1. Go to the basic settings tab, and pull the slider all the way to the left.
2. Render from those settings
3. Move the slider up and render again.
4. Repeat until you get to a view you like, or until Poser can't handle it anymore.
5. Use the settings on the last working render to adjust the Advanced settings.

From the settings you posted, I would increase the Bucket Size, and the Min Displacement Bounds, unless you have a specific reason for having such a high displacement setting. Considering you mentioned you haven't touched the Mat Room, I'll assume you aren't doing any displacement. In that case, set the Min Bounds to a number like 1.000, to stop the render engine from trying to make those calculations unnecessarily.

HTH!
